PTFE Silicone Septa for Environmental Testing

PTFE/Silicone septum is provided with a thin 0.005” PTFE layer laminated to our high purity silicone and slit through the center to provide for easier needle penetration as well as to release the vacuum that forms when a large volume of sample is withdrawn from a vial.

PTFE/white silicone purepack septa Excellent choice for general volatiles analysis. Septa are packed in a glass PurePak jar to assure low background, low permeability, and the highest performance of any headspace septum. PTFE/Silicone septa provide excellent resealing characteristics and broad chemical compatibility.
